In the semiconductor industry, the quality of compressed air is critical to the stability of the production process and product quality. Especially for particle numbers of 0.1 microns, the requirements are usually very strict to ensure the cleanliness of the production environment.
Standards and requirements:
although there is no uniform international standard that specifies a specific upper limit on the number of 0.1-micron particles in compressed air used in semiconductor production, some general guidelines are generally followed in the industry.
Some high-end applications may require that the number of 0.1 micron particles in the compressed air is less than a certain order of magnitude, such as less than 100/m3, to ensure the cleanliness of the production environment.
Detection difficulty:
the detection of 0.1 micron particles is difficult because these particles are very small, difficult to directly observe and detect, and are susceptible to factors such as Brownian motion.
Highly sensitive instruments and techniques are required to effectively detect these particles.
Industry Practice:
in the semiconductor industry, especially in clean room environments, 0.1 micron dust particle detection is very important.
The air cleanliness level of dust-free workshops in the semiconductor industry is usually required to be level 7 or higher in the ISO 14644-1 standard, which means that in the dust-free workshop, the number of dust particles with a diameter greater than 0.1 microns per cubic foot of air should not exceed 100.
Recommendations and measures:
for the specific semiconductor production environment, it is recommended to refer to the relevant process requirements, equipment manufacturer's recommendations or industry best practices to determine the acceptable range of 0.1 micron particles in compressed air.
Regularly testing and monitoring the quality of compressed air is also an important measure to ensure the stability of the production process and product quality.
In summary, the number of 0.1 micron particles of compressed air used in the semiconductor industry should be as low as possible, usually less than a certain order of magnitude (such as 100/m3 or less) to ensure the stability of the production process and product quality. The specific value may vary due to different production processes and equipment, so it is necessary to evaluate and make decisions based on actual conditions.
At present, most domestic cities use centralized landfill or incineration for garbage disposal. Compared with landfill methods that are easy to pollute the soil, waste incineration treatment is more conducive to reducing the volume of waste and eliminating various pathogens. Moreover, with the sustainable construction of society
